CARDAMOMUM. 
Spaeth, E., points out that the amount of mineral matter in card- 
amom seeds varies materially, and that too much stress should not be 
placed on the ash content. A minimum requirement for the essential 
oil is considered desirable. He also points out that commercially 
satisfactory ground cardamom should consist only of the ground seed, 
and for this reason the microscopic characteristics of the hulls should 
be adequately described. The minimum content of essential oil is 
suggested as 3 per cent. Powdered whole fruit should be declared 
as such. The maximum ash content of the seed should not exceed 
10 per cent, and the amount insoluble in 10 per cent hydrochloric 
acid should not exceed 4 per cent. The ash content of the whole 
fruit should not exceed 14 per cent, and the amount insoluble in 10 
per cent hydrochloric acid should not exceed 4 per cent. — Ztschr. f.

An abstract from the report by Hein. Haensel, in Pirna, reports 
the study of a variety of cardamom sent from West Africa, said to 
be the fruit of Ammomum korarina di Pareira, which on distilla- 
tion yielded 1.72 per cent of a volatile oil. — Pharm. Ztg., Berlin, 1905, 
v. 50, p. 929. 
Just’s Botanischer Jahresbericht (for 1905), v. 33, part 3, p. 752, 
contains several references to the cultivation of cardamom and the 
preparation of the drug for market. 
CARBO LIGNI. 
Lloyd, John Uri : “ The intent is to use the charcoal made from the 
willow, freshly burned, and finely powdered, but the fact is, few 
who handle powdered willow charcoal know whether it is obtained 
from the willow, the beech, or some other tree. Nor do they know 
whether it has been exposed to the action of the air and ab- 
sorbed therefrom a load of gas products that may be carried into a 
remedy.” — Pharm. Review, 1905, v. 23, p. 299. 
CARUM. 
Eberle, E. G., mentions caraway as being one of the medicinal 
plants now found or grown in Texas. — Proc. Am. Pharm. Ass., 1905, 
v. 53, p. 304. 
Spaeth, E., points out that extracted seeds are to be classed among 
the more common adulterants of caraway, and he therefore believes 
that the microscopic characteristics of the fruit should be added to 
an official description, as powdered caraway is frequently sold. 
Commercially satisfactory caraway should be required to consist of 
the undamaged seed of caraway that has not been deprived, either
